一个日处理1000t的中型糖厂,每天排出的滤泥大约100t,一个制糖周期,积累量达2万多t,如不及时处理或利用,不但占地面积大,而且将严重污染环境。经综合分析,滤泥含有机质6.57％,有效钙含量为1.13％,全氮量0.33％,全磷量1.15％,水解氮72.22mg/100g土,速效磷17.37mg/100g土,速效钾14.25mg/100g土,pH值8.6,并含有较丰富的微量元素Cu、Zn、Fe、Mn、Mo、Mg等。为变废为利,我们分别于1978、1987、1988 A daily processing of 1000t medium-sized sugar mills, daily discharge of mud about 100t, a sugar cycle, the cumulative amount of more than 20,000 t, if not handled or used, not only covers an area of ​​?? large, but will also seriously pollute the environment. After comprehensive analysis, the content of organic matter in filter mud is 6.57%, effective calcium content is 1.13%, total nitrogen content is 0.33%, total phosphorus content is 1.15%, hydrolyzed nitrogen is 72.22mg / 100g soil, available phosphorus is 17.37mg / 100g soil, available potassium is 14.25mg / 100g soil, pH 8.6, and contains more abundant trace elements Cu, Zn, Fe, Mn, Mo, Mg and so on. To turn waste into profit, we were in 1978,1987,1988
